WARNING
Outside the U.S.
Gasoline is extremely flammable and highly
explosive  under  certain  conditions.  Follow
the  instructions  in   this  section  explicitly.
Improper  handling  of  fuel  could  result  in
property damage, serious injury, or death.
Your outboard has been designed to operate using
the above fuels; however, be aware of the follow-
ing:
The boat’s fuel system may have different require-
ments regarding the use of alcohol fuels. Refer to
the boat’s owner Guide.
Always turn off the engine before fueling.
Alcohol attracts and holds moisture that can cause
corrosion of metallic parts in the fuel system.
Never permit anyone other than an adult to
refill the fuel tank.
Alcohol  blended  fuel   can  cause  engine  perfor-
mance problems.
Do not fill the fuel tank all the way to the top,
or fuel may overflow when it expands due to
heating by the sun.
IMPORTANT: Always use fresh gasoline. Gasoline
will oxidize and weather; the result is loss of octane,
volatile compounds, and the production of gum and
varnish deposits which can damage the outboard.
Remove  portable fuel  tanks  from  the  boat
before fueling.
Always wipe off any fuel spillage.
WARNING
Do  not   smoke,  or  allow   open  flames  or
sparks,  or  use  electrical  devices  such  as
cellular phones in the vicinity of a fuel leak
or while fueling.
Leaking fuel is a fire and explosion hazard.
All   parts  in   the   fuel  system   should   be
inspected  frequently  and  replaced  if  signs
of   deterioration    or   leakage   are    found.
Inspect   the  fuel   system   each   time  you
refuel,  each  time  you  remove   the  engine
cover, and annually.
Always work in a well ventilated area.
Your outboard is certified to operate on unleaded
automotive gasoline with an octane rating equal to
or higher than that specified in Minimum Octane
chart. When using gasoline that contains MTBE or
alcohol, follow these guidelines:
Using unleaded gasoline that  contains methyl ter-
tiary butyl ether (MTBE) is acceptable  ONLY if the
MTBE content does not exceed 15% by volume.
Using alcohol-extended fuels is acceptable ONLY if
the alcohol content does not exceed:
10% ethanol by volume; or
5% methanol with 5% cosolvents by volume
